CAR-DUMPING DEVICE.

Specification of Letters Patent.

Patented Dec. 6, 1916.

Application filed March 28, 1910. Serial No. 551,948.

T 0 all whom it may concern:

Be it known that I, JAMES H. BnRRYMnN, a citizen of the United States of America,

residing at Tacoma, in the county of Pierce and State of Washington, have invented certain new and useful Improvements in Car- Dumping Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to devices for unloading railroad ca-rs and especially to devices whereby the entire contents of each car are dumped at the same place as the car passes.

It has for its object to provide a device which may be readily applied to any ordinary flat car without altering the construction thereof or without injuring any of the parts thereofto such an extent as in any way to prevent the car being used as a flat car immediately on removal of the mechanism of this invention.

Other objects are to provide a device which will automatically operate whenever the car reaches the dumping place and will not work at any other place; which is simple and cheap to make and to install and which may be used for dumping a large variety of materials.

I attain these and other objects by the devices illustrated in the accompanying drawings, in which- Figure 1 is a side elevation showing one car in the act of dumping a load of logs, and another car with the dumping apparatus placed in its inoperative position; Fig. 2 is an end view of a car dumping a load of logs; Fig. 3 is an end view of a gondola car dumping a load of dirt or other similar materials; Fig. 4 is a side elevation of a gondola car; Fig. 5 is an end view of a flat car equipped with my improved dumping device; Fig. 6 is a side view thereof.

Similar numerals of reference refer tosimilar parts throughout the several views.

When this invention is used for the dumping of logs or similar objects, as in Figs. 1, 2, 5 and 6, it consists of avertically movable bunker, means for securing the bunker to the fiat car, and means for raising one end of the bunker to dump the load thereon; but when it is used for materials such as dirt, rock, coal or other similar materials, (Figs. 3 and 4), the box or gondola containing the said load is mounted on the said movable bunkers and is independent of the flat car which supports it, and is operated by the movement of the bunkers.

Referring now to the drawings, the bunker 1 consists of a heavy beam of wood incased on each side by heavy iron plates 2, and secured to the flat car 3 by means of pins 4 which pass loosely through holes made in the deck of the car 3. The dumping end of the bunker 1 is practically in line with the edge of the car, but the other end thereof extends out a few inches beyond the side of the car. An eye-bolt 5 passes vertically through this end of the bunker 1,

a heavy iron plate 6 being placed between the eye end of the bolt and the wooden bottom of the bunker 1. A lifting bar 7, which is forked at both ends, is secured at its upper end by a pin 8 to the eye-bolt 5. A roller 9 is mounted in the fork at the lower end of the bar 7. A tension rod 10 is hooked to the lower end of the lifting bar 7 and extends therefrom lengthwise of the car and hooks over a nger 11 which is secured to the deck `'of the car 3 and which extends out sidewise therefrom. The tension rod 10 has a suitably positioned offset 12 formed about midway of its length, which offset is adapted to engage the said linger 11 when the lifting bar 7 has been turned up to its horizontal or inoperative position, so as to hold the lifting bar up and out of the way.

The lifting bar is actuated by means of a third rail 13 which is laid in suitable position outside of the rails forming the track on which the car 3 moves, but substantially parallel therewith, said rail 13 being supported in such a manner as to gradually rise from its lowest position, which is preferably slightly below the level of the rails of the track, to its elevated position which would in practice vary somewhat with the materials to be dumped but which would be some 15 to 30 inches above its lowest position. The rail 13 extends at its highest position for a sufficient length to give time to dump all the contents of the cars as they pass along the track at the dumping place.

Then a gondola (Figs. 3 and 4) is used it consists of a box 14 secured to the bunkers 1 and having the dumping side 15 thereof suitably hinged to allow the load to pass therefrom when it is tipped as above described.

Having described my invention, what I claim is 1. In a car-dumping device, the combination of a load-carrying car; a vertically movable bunker mounted on the car and under the load; a lifting bar mounted on the said bunker and adapted to raise one end thereof; a tension rod secured to the car and to the lifting bar to brace it; and an inclined and elevated rail adapted to be engaged by the lifting bar and adapted to raise said bar and one end of the bunker to dump the load thereon as the car moves therepast.

2. In a car-dumping device, the combination of a load-carrying oar; a vertically movable bunker mounted on the car and under the load; a lifting bar mounted on the said bunker and extending downward therefrom, but adapted to be swung into substantially horizontal inoperative position; a. tension rod adjustably secured to the car and to the lifting bar to brace it in either of said positions; and an inclined and elevated rail adapted to be engaged by said lifting bar whenin its vertical position and adapted to raise said bar and one end of the bunker Vto dump the load.
